use Samsung Galaxy BudsSamsung Galaxy Buds is Samsung's first wireless earbuds for Android devices, although you can also use them on iOS, Linux, or Windows devices.

This wireless earbuds guide explains everything you need to know about Samsung Galaxy Buds  (and Samsung Galaxy Buds Plus):  box contents of the buds, the layout of the buds, how to use the buds, how to charge the buds, how to check the battery status, how to pair the buds with other devices, how to use touchpad commands to control the buds. A concise review of the Galaxy Buds was also included.

Of course, some questions you may have on Samsung Galaxy Buds and Samsung Galaxy Buds Plus were also answered. So, this guide covers both Samsung Galaxy Buds and Galaxy Buds Plus (Galaxy Buds+).

Please note, Samsung released Galaxy Buds Live with Galaxy Note 20. Because of the new active noise cancelling (ANC) feature and new design, you may check this page (coming soon) on how to use Galaxy Buds Live. Galaxy Buds Pro was released with Galaxy S21 in Jan 2021 with some new and improved features (compared to Galaxy Buds Live).

What is Samsung Galaxy Buds?

Samsung announced Galaxy Buds, a wireless earbud for Android phones, together with the Galaxy S10 in March 2019.

Prior to Galaxy Buds, Samsung already offered Gear IconX as a fitness (and wireless) earbud.

Galaxy Buds is smaller and lighter by removing the built-in storage and workout-tracking ability in IconX. If you need earbuds for a workout with a heart rate monitor, the best option is the Jabra Elite Sport.

So, you can think Galaxy Buds is the wireless in-ear earbuds for Android phones matching AirPods for iPhones.

In 2020, Samsung updated Galaxy Buds with Galaxy Buds+ (Galaxy Buds Plus) with longer battery life, better sound and audio quality as explained in this guide. The MSRP price is $149. In many regions, Samsung Galaxy Buds+ is bundled with Galaxy S20 as a free gift.

What devices are compatible with Galaxy Buds?

The official spec sheet of the Galaxy Buds requires Android 5.0 and Galaxy Wearable app.

But this is for “quick” pairing.

In fact, you can use Samsung Galaxy Buds as a normal Bluetooth headset. Therefore, you can use the Samsung Galaxy Buds with most devices that support Bluetooth audio, for example, iPhone, Windows PCs, and laptops.

What is active noise canceling (ANC)? How active noise-cancelling headphone works?

What is active noise cancelling (ANC)? How active noise cancelling headphone works?You need an active noise cancelling (ANC) headphone if you want to block the ambient low-frequency noise, like engine noise in the aeroplane. For example, Sony WH-1000XM (XM1-XM4) series, Bose Quietcomfort series (e.g., 15, 25, 35, earbuds), Apple AirPods Pro, and Samsung Galaxy Buds Live all have ANC.

Active noise cancelling (ANC) is different from noise blocking/isolating, which passively blocks both high and low-frequency noises.

This headphone guide explains what the active noise cancelling (ANC) is and how the active noise cancelling headphone works. It will not only help you understand ANC but also help you choose proper active noise-cancelling headphones.

What is active noise cancelling (ANC)?

Active noise cancelling (ANC, aka active noise control) is a set of audio technologies that actively cancel the ambient noise.

Both the annoying noise and music reach your ear as sound waves transmitted through the air.

So, one simple way to reduce noise is to physically and passively block it. For example, there are many soundproofing materials and technologies.

In the airport, you may notice ground staff are wearing earmuffs to block the engine and other noises. In the shooting clubs, it is also common that earmuffs are used.

Active noise cancelling (ANC),  on the contrary, uses negative sound waves to actively cancel the noise.

This means ANC requires at least three components:

  • Power source.  Active noise cancelling (ANC) always requires a power source to detect and analysis noise and then generate a negative wave.
  • Noise detection. Normally, one or more microphones are used to sample the ambient sound.
  • Anti-noise sound wave generator. Once the ambient noise is sampled, an active noise cancelling (ANC) system must generate an inverted (negative) sound wave (with similar amplitude) to cancel the low-frequency noise.

When the ambient noise is cancelled, you will get a quieter environment for your music.

Active noise cancelling (ANC) is still evolving, especially on how to sample ambient sound, how to analyze the sampled ambient sound, and eventually how to effectively cancel the low-frequency ambient noise in real-time.

Please note,  active noise cancelling (ANC) currently is most effective for low-frequency noise only.

Active noise cancelling (ANC) vs passive noise blocking

As discussed earlier, noise can be “blocked” (passive)  and/or  “cancelled” (active).

Most headphones, in-ear or on-ear or over-ear, can block certain ambient sounds. For example, some in-ear headphones are designed to seal the ambient sound (e.g., Sony … Read the rest
